Hair Brush

Abstract

This brush is made up of: a handle (1); an aluminium tubular body (2) which is coated with an artificial plastic material, vinyl fluoride polymer, and holes (21) with polygonal shape, arranged in a herringbone pattern, which end in bevelling (21, 21b) and are arranged forming oblique lines in respect of the longitudinal axle of the brush; nylon fibres (41), ionized by means of radiation, fixed helicoidally to a supporting centre (4), located inside the tubular body, emerging the said fibres (41) through the holes (21) of the tubular body, and a front top (3) that closes the fore end of the above said tubular body.

Description

OBJECT OF THE INVENTION[0001]This invention is about a hair brush like the ones used for hair straightening and soft perms which feature: a handle, a holed tubular body through which emerge fibres that are fixed helicoidally to a support centre, and an upper top that closes the fore end of the said tubular body.BACKGROUND OF THE INVENTION[0002]Nowadays the use of hair brushes is common for hair brushing and soft perms either at home or in hairdressing and beauty salons. An example of commonly used brushes in hairdressing salons are the ones which comprise a hollow and holed tubular body which has got a handle for it to be held on one end and a top to close it on its other end being inside this tubular body a bunch of fibres arranged helicoidally which come out through the holes of the said tubular body. This kind of brushes allows making a soft perm and a hairdo while applying heat.[0003]In these brushes the tubular body is made in aluminium coated or not with ceramic which allows t...

Benefits of technology

[0012]Furthermore, the coating of polytetrafluorethylene makes the time of heat transfer to be prolonged and provides a proper protection against the damage of the brush caused by the action of components in products applied on the hair, giving thus a longer useful life to the brush. Additionally, due to the non-stick properties of this coating material, a smooth sliding of hair over the tubular body of the brush is granted avoiding thus any pulling of the hair and also seals the hair cuticle obtaining thus as a result a more brilliant and reinforced hair than with the use of conventional brushes.

[0015]The fibres of the brush are made of nylon ionized by means of radiation, which provides more strength and resistance to them during its use due to the alteration produced in their molecular structure during the radiation. The use of these ionized fibres favours the sliding of hair among them, avoiding the accumulation of static in the hair and therefore the undesirable effects that carries such accumulation.

Problems solved by technology

When the tubular body is coated with ceramic it accumulates calories for more time than just aluminium but transmits heat with less speed and effectiveness.

Another known inconvenient of this kind of brushes is that the hair products applied adhere on the tubular body little by little avoiding thus a smooth and uniform sliding of hair on the said tubular body.

Furthermore, another inconvenient of this kind of brushes lies in the fibres when emerging through the holes of the tubular body because they do not come out perpendicularly to it due to the fact that normally the holes are circular which cause most of the fibres to lean slightly avoiding the hair sliding smoothly over the brush and making effective contact with the surface of the tubular body, reducing thus the effectiveness of the brush notably, specially during the straightening and soft perm works.

The presence of these imperfections becomes an important problem during the assembly of the different pieces that compound the brush or during the use of it, because in the case of these imperfections remaining at the internal side of the tube they become a means of retention for the fibres to come out through the tubular body, whereas in the case that the imperfections are on the external side of the tubular body they are so jagged that can damage the hair cuticle.
